Zotero is getting better and better. In a while, version 1.5 will bring synchronization, online backup of your library, +1100 
CSL citation styles, and PDF metadata extraction (for the daring, a 
sync preview
 version is available). But even in its current incarnation Zotero is 
easily one of the best bibliographic managers out there. Here are twelve
 tips and tricks that help you to get the most out of it.
- Drag files from the web right into your library
 Got a reference in your library, but no PDF? Or saved an item from a 
repository which doesn’t provide a fulltext version? Do a quick search 
for the title on Google Scholar
 — it is good at finding PDFs on author’s webpages. If you find one, 
just drag the link from the page onto the reference in your library. 
Zotero stores and attaches the PDF for you.
- Enter a series of items by duplicating a template
 Adding a series of related references to your library? Start with one 
item for which you fill in the fields that are the same for all items 
(e.g. editors, book title, year, publisher, place) and duplicate it 
(Right-click > Duplicate item). Then fill in the particularities.
- Quick Copy a citation using Ctrl+Alt+C or drag and drop
 Sending a PDF to a colleague, or mentioning a reference somewhere? 
Quickly copy the citation by selecting the reference and pressing 
Ctrl+Alt+C (Command+Alt+C on the Mac), or simply drag it from Zotero 
onto any edit window (for example a new email). The default output style
 can be specified under Preferences > Export; the shortcut key can be
 customized under Shortcut keys.
- Have Zotero index your PDFs
 Zotero can index your PDF attachments and make them fully searchable, 
turning your library from a mere linked catalogue into a Google Books of
 sorts. The option is turned off by default because it relies on an 
external open source program (pdf2txt) which is not distributed with 
Zotero. However, Zotero can automatically install it and enable fulltext
 indexing: simply go to Preferences > Search and click on the ‘Check 
for installer’ button. For more info see pdf fulltext indexing in the Zotero documentation.
- Start quicksearch with ” to trigger advanced search
 By default, Zotero starts searching when you put the first few 
characters in the Search box. In a large library with fulltext indexing 
enabled, this can be tiresome (you wanted to look for “statistical 
methods”, but Zotero locks down searching for “st”). To avoid this, 
simply start your search with ” (double quote) to have Zotero wait until
 you finish typing and hit enter.
- Press Ctrl to find out in which collections an item is
 Looking at an item in your library and wondering whether you already 
categorized it? Press Control and Zotero will highlight the collections 
in which it is contained.
- Relocate your Zotero folder to a more sensible place
 The default place for the Zotero database and attachments in right in 
your Firefox profile, which isn’t the easiest to locate whichever OS you
 are on. Go to Preferences > Advanced to customize the storage 
location. You can place it in a folder that is included in your regular 
backup schedule or put it on a portable drive so that your library 
always travels with you (tip: combine it with Firefox Portable, which you can even use without administrator rights).
- Keep track of recent additions using a saved search
 Often you add new items without worrying about tagging or putting them 
in collections. Click Advanced search, select “Dated Added” > “is in 
the last” > X “days/months” and fill in the desired period; then save
 the search. This gives you a dynamically updated overview of your 
latest additions, so that you can go back to them and do the 
categorization and tagging work when it suits you.
- Tag multiple items at once
 Want to tag multiple items at once? Select them, make sure the tag 
selector is visible in the left pane, and drag them onto the tag you 
want to use. The tag will be applied to all items.
- Tag incomplete items to find them back and fix them later
 Sometimes you know an item has incomplete metadata (e.g. missing page 
numbers or publisher), but you don’t have the time to fix it right away.
 Make it a habit to tag such items (“needs metadata”) when you see them.
 Now you can find them and fix them whenever you have some time to kill.
- Use a separate folder for files to be ingested
 Someone gives you a bunch of PDFs to read; or you download a paper 
somewhere without having the metadata handy. Make it a habit to save 
such files in a subfolder /new/ in your Zotero folder. Then once in a 
while go through that folder. Do a quick search for the title on your 
favourite repository,
 grab the metadata, and then drag the PDF from your filemanager onto the
 reference in Zotero. Much better than having those loose PDFs scattered
 all over your hard drive (or in your mailbox!) — and it helps you keep 
track of your reading history too.
- Display a timeline to visualize your bibliography
 Not a feature you’ll use everyday, but a neat one nonetheless: Zotero 
can display your library, or portions of it, on a timeline. Select a 
group of references, a tag, or a collection and click ‘Create timeline’ 
(in the Gear menu). This gives you an overview of the items in time. Now
 you have to ask yourself: is the recency bias due to your reading 
habits or is it really true that most of the research was done in the 
last twenty years? (Probably a bit of both.)
