Essentially, Pubmed is the public interface to MEDLINE (e.g., Ovid also has/had a subscription-based interface to it). Pubmed Central is an NIH repository containing free full-text of some of the articles indexed therein. Do you need to know much more than that? (Sorry, I know you didn't ask, I'm just procrastinating) - Meg V. Meg

Wat Meg said. Also, thinrgs can show up in PubMed before they show up in MEDLINE, esp. Epub ahead of print. Automatic term mapping is improving all the time. PubMed includes clinical queries and filters. It is cross indexed with lots of NCBI, NLM, NIH tools, which is helpful and cool. The only "advantage" ofmMEDLINE, imo, is that some people like other search interfaces better (I still like OVID) or they like being able to search MEDLINE and CINAHL on the same interface. - maʀtha

I need to know tons more. :) What things like [PubMed - in process] , [PubMed - indexed for MEDLINE] etc means. How it interacts with stuff like PLOS, Pubmed central, free stuff on publishers. PMID assignments (when) etc.. Goal is to understand best way to get full text with various options including linkout tool. I *think* I know how linkout works thankfully but without background on the rest is a bit hard to understand why sometimes it doesn't work. Eg I got a libx toolbar that hot-links pmids on pubmed to our link resolver..Why does it fail sometimes to pubmed central? or even PLOS? - aarontay

Going through http://www.nlm.nih.gov/bsd... now.. So many terms.. NCBI, Entrez, NLM. Medline is like the main part of pubmed.. everything there is indexed using MESH. Pubmed has slightly more stuff beyond that. Pubmed central is like all the free OA stuff? Not sure what the heck is medlineplus... - aarontay

That's consumer health/medicine info. - Meg V. Meg

Medlineplus is awesome and the name is totally misleading and stupid. It has nothing to do with MEDLINE except that it is also from NLM. It is a fantastic health information resource for patients, families and health care consumers. It includes a medical dictionary, medical encyclopeida, vitatins and supplements database, drug database, tutorials, surgery videos and more. Many pages are translated into a whole bunch of languages. There is a special senior health section wich various font sizes. The health topics pages are awesome. They like to outside pages which are all vetted by medical librarians. They also link to citations in PubMed. It is s fantastic source of health information designed for the lay person. - maʀtha

I must say searching for medical stuff is really complicated. No wonder, medical students, flock to librarians to learn how to search. Pubmed is really hard core. - aarontay

Dude, the algorithm is fantastic these days. - Meg V. Meg

You need to use the outside tool with your open url lnker (360?).you should have Plos in your SerSol knowledge base, along with DOAJ. PubMed Central is the repository for papers from studies that received NIH funding, per the congressional mandate. Publishers have to put the papers that include results of these studies into PubMed Central. - maʀtha

Yes, the automatic term mapping is about fives times better than it was five years ago. The PubMed tutorials are great. - maʀtha

We wont support document delivery via openurl so no outside tool. :( - aarontay

Yes, but no one but a librarian would read through 12 pages explaining what each status is though... - aarontay

I think you need the outside tool for the open url linker, right? Sme serials librarian correct me if Im wrong. Do I have them reversed in my head? - maʀtha

Okay I give up. Too much detail, try again tomorrow. - aarontay

Yes we are 360link institution.. We have turned on PLOS in the knowledge base, but not DOAJ. I find some PLOS that fails when going through pmid not sure what is up with that. But i suppose if someone is searching pubmed..the free stuff they wont have problems getting there, is the non-free stuff that is an issue, basically the stuff we have in LWW/OVID. - aarontay

http://www.ncbi.nlm.nih.gov/books... - maʀtha

Okay, I think we went iwth outside tool so that our find it link will show up in evrery record in pubmed, which would either direct users to the full text in our subscriptions or to our ill form. - maʀtha

Pubmed Central is just some of the free full text available right? Some publishers also offer free full text? These are considered different? Or all covered under PMC? And btw what's the relationship between NLM and NIH? - aarontay

Dm me and I'll search my notes and email at work to confirm all of this set up stuff. We really wrestled with this set up, so I know I have notes. I can also answer some of your other questions. Sorry for the overwhelming detail. I'm happy to help, if I can. - maʀtha

PubMed Central is different from publishers offering free fulltext. It's a repository. - Meg V. Meg

Thanks martha for the kind offer. It really sounds difficult, though the help file at SS seems to imply it's easy.... - aarontay

http://www.ncbi.nlm.nih.gov/project... is basically the decision tree. LinkOut via Submission Utility is used when you have no openurl service, so is dependent on the publishers adding data via linkout. Obviously we not going for that. Outside tool and Iinkout local are both using the openurl resolver, except for linkout local you need to give your holdings in xml. Outside tool doesn't require you submit your holdings so Pubmed doesn't know what you have and will put the openurl icon on all citations (basically like most databases). Linkout local does know what you have, so it selectively places the icons. Linkout local is kinda like how Library links program works with Google scholar as both require you upload your holdings. Because pubmed knows what you have, you can selectively show only results where you have access. You can also have different icons for print vs online if you upload print holdings. Linkout local needs you or your openurl provider to manage XML holdings. Outside tool requires you pass a few "tests" before allowing it to work in particular a openurl enabled ILL form. Does that cover it? - aarontay

Yep. We went with the Outside Tool because we *want* the Open URL linking icon to show on all records in PubMed because we want folks to be directed to our interlibrary loan form if we do not subscribe to the article in full text. We also want users to see all records in PubMed. - maʀtha

We have 360 set so that the open url links always go straight to the target with the full text instead of to the intermediary page. If you have your settings like this, you have to get SerSol to turn off the direct linking for PubMed only. They can do this, but you have to contact SerSol directly. - maʀtha

And, yes, the set up with NLM for PubMed is a pain. If you need assistance, you can contact NLM directly at http://www.nlm.nih.gov/bsd.... - maʀtha

Also, I just found out that there is an international section of MLA, who knew (http://ics.mlanet.org/)? - maʀtha

Looks like martha has covered a ton of stuff and may have dealt with your questions. If I can help let me know, though, or just keep posting questions here. Couple of quick notes: In Process and Supplied By Publisher items haven't been indexed yet. Term Mapping may be better, but it's not perfect - try searching just for lupus with no qualifiers and expecting SLE, for example, or HRT expecting it to map to hormone replacement therapy. If you have to learn about PubMed Central, you might also want to know about the NIH Public Access Policy - http://publicaccess.nih.gov/ - Rachel Walden

Yeah, I still teach MeSH and other advanced techniques, but I am impressed at how much better the ATM is. Thanks for the lupus and HRT examples! - maʀtha

No problem! Those are the examples I've been using with new residents this year. - Rachel Walden

What Meg said up top is so right. The algorithm is awesome. I can get similar results sets from keyword searching that I would get by building a MESH search. I do not usually bother with MESH, though our health sciences person still insists on teaching it to students who don't understand it or care. - kaijsa

yeah, I think it depends on the audience and the need - maʀtha

All depends on context. I teach MeSH as part of the Evidence based practice class, where students have to use it with assignments. I expect as they get more comfortable with medical literature they fall back on keywords but I'd like them to at least have a solid idea how to use it. It's definitely harder if you're trying to stuff it into a one-off though. - Hedgehog

I'm sure there are differences by environment, etc. Our medical residents absolutely love learning about MeSH, because they can see how that helps them think of other terms, make sure they're using the right terms, etc. They're usually really relieved to learn about that feature, as it gives them a measure of control they didn't have before, along with the suggestions. When I do my one-offs, I don't do every single PubMed feature - we barely touch on limits except to say "they're there, play with them.". I explain to them how and why to use both MyNCBI and MeSH, to be more efficient and more thorough in their searching. And how to get help from us later if they need it. - Rachel Walden

(we do a couple of extremely basic searches that allow me to demo both of those things, plus let me work in a couple of other key points.) - Rachel Walden

I also explain to them that if they just need one thing on a topic to brush up, keywords may be just fine. But if they're working on a grant, review, etc. and want/need to be thorough, then here are some things they can try... [okay! I'm done now! except to say that *how* you teach it makes a tremendous diff btw sleeping audience and psyched audience] - Rachel Walden

I should have said I don't teach ANY health sciences classes, but might work with FY students at some point. At the desk, there is generally not a need for all the details. - kaijsa

God, I love it when the medlibs start to geek out. :D - laura x

*snork* I just spent my entire last consult thinking of y'all. Neurosurgical resident who thinks Saved Searchers are greatest thing since sliced cheese. - Hedgehog

nice :) - Rachel Walden

I am halfway through the tutorial. enjoying the level of detail eg on how ATM works. don't know many medical terms but am librarian enough to appreciate the power of mesh headings and auto exploding. makes me wonder how powerful tools like summon would be with such deep controlled vocab. also I am surprised to note that the systematic review option in clinical tools is actually a canned search strategy not an assigned heading/pub type? that's basically what I am trying to do to pull up survey articles in other areas. - aarontay from BuddyFeed

I have always thought that systematic review thing is weird, too - not sure why they don't just assign a pubtype. They do for meta-analysis. Weirdness. - Rachel Walden

I thought it had moved into pub-type with the limits change. No? - Hedgehog

Apparently not. In select on filters http://www.ncbi.nlm.nih.gov/books... it says "Click the “more …” link, to add additional article types,, and then click apply. The complete list of MEDLINE publication types is available. Systematic review articles are produced using a search strategy." - so the rest are pub type but systematic review isn't. - aarontay

Naive question. It seems we have access to Medline via Proquest (new platform). Thus far, I am not sure why someone would bother to use it rather than via Pubmed. For Relevance ranking? The ability to stick in the openurl resolver easily? not sure if the interface is really better. - aarontay

I don't know either. I still like the Ovid interface, but it is how I was trained - maʀtha

Me too, Martha. - Meg V. Meg

Not sure about Proquest. Some folks like Ovid because of adjacency operators. We teach PubMed b/c no matter where they end up they'll still have access. - Rachel Walden

yeah over here we teach pubmed also. I am just curious because recently moved from medline CSA to new proquest. - aarontay from BuddyFeed
