Is there a good overview of all the online bioinformatics databases available in this world? I often thought it would be helpful to have an up-to-date overview of what databases there are, if and by whom they are curated, what their specialization is, and potentially some qualitative assessment.
I am thinking of a very broad catalog of databases, from gene databases, and interaction databases, to literature databases, and whatever else you can think of.
The closest thing is probably the annual NAR Database issue, which is easy to criticise, but does do a pretty good job of rounding things up. It is relatively easy to search, and seems to get more comprehensive every year.
On a related, but slightly off-topic note, there is BioCatalogue, which is a database of web services. I guess you're after something similar?
Bioinformatics Link Directory covers all the resources in NAR and additional resources curated from literature. Developers can also submit the details about databases/tools which are not listed.
Manuscript describing different version of Bioinformatics Link Directory are available here

[?]Most of the resources are from the servers and databases issues from NAR. I just tried to link some tags to each resource. Tags are located on the right sidebar.[?]
We have a curated one at http://www.openhelix.com that is publicly available. It has almost 700 and growing. The search ranks by several relevant criteria (keyword context), usage, etc.
Well... now there is a database of databases, its human genomic only, but it is the largest portal for human genomic data in the world with 1.1 million datasets. And it's FREE! https://repositive.io
Magdalena, I suggest Pierre's answer of today to be picked as solution.
