Our new toy here in the library is Pubget. Its a database which aims to quickly retrieve results and link out through to the PDF.
The first instinct will be to type basic keywords in the blank box to quickly retrieve the first PDF files. It is indeed quick. But remember you can specifiy your results better in the advanced search area.
Search options in the advanced form are sufficient to satisfy most of us, with advanced search fields like PMID or DOI numbers, MeSH terms, etc..
Pubget say that their export format is compatible with Zotero, EndNote and RefWorks. But I have to say I have found limited functionality here on this score with the results only exporting one at a time. More testing needed- and feedback welcomed- Please comment.
The primary goal is to open PDF files as fast as possible. And I can testify that it does work pretty darn well at this.
