StudyCollect

I study ,I use StudyCollect software.

If you need a document organizer,try it.
This software primarily contain two objects--Subject and Document.
If you link a document to a special Subject, then this special Subject include that document.Certainly you can cancel this link.A special subject can include several documents.
The most Advantage in this software is a document could be linked to several special subjects and When you click the document Title,you could see which subject is linking to the document immediately.
The features is helpful for your research. We wish this software would like your research assistant.

IF you cancel the link,the subject could not include the document,but the

document still exist.If you delete the document,so the document is deleted.

The links of the document are deleted also.
