Zotero helps you build a database full of references that you’re free to use for researches.
It is also a good complement to the bookmarking system of browsers.
Zotero provides a free cloud storage up to 300 MB.
There are several paid plans to get more storage space.
The software supports Mozilla Firefox, Google Chrome, Microsoft Edge, and Safari.
The extension is not mandatory, but it will make things much easier.
you might expand the dialog box to add tags and select a folder where the reference will be stored.
However, you have to create the folder first in the main interface of Zotero.
The dialog box only allows you to select a folder, not to create.
The snapshot is optional.
By default it saves the reference in HTML format.
Double-clicking on the snapshot will open it in your default internet tool.
Fortunately, Zotero provides a context menu to initiate the folder of each snapshot.
Sometimes, when you add an item to Zotero, tags are added automatically.
you’ve got the option to disable this automatic tag and manually add tags as you see fit.
Up to 9 tags can have colors to locate specific items more easily.
The red square appears at the beginning of every item in the item list.
Apart from folders and tags to organize your references, you’re free to use saved searches.
There is no way to organize the saved searches, however.
Your library will look cluttered the more you save searches.
But if you do create one, a 300 MB space will be yours, for free.
Zotero abilities can be extended by installing add-ons.
