This library has an impressive collection of resources from a range of different disciplines, including art, design, science, philosophy, social sciences and humanities, and foreign languages.
You need to pay to access the collection, but the annual subscription fees are not expensive if you plan to use the collection regularly.I paid 20 euros for an annual student subscription - however, I wasn't expecting to pay anything so was surprised when I arrived!
There is also free Internet usage at selected terminals, although this is usually limited to one and a half hours per session.
For me, the collections are impressive but I did not find this a conducive place to work as I didn't have my own laptop at the time. You can't use a USB stick in any of the computers and most of the libraries had dim lighting, which did not maximise the use of the large windows facing the interior garden.
There are multiple vending machines for refreshments throughout the library - surprisingly serving some of the best coffee for 1 euro I've had in Paris! There is also a small cafe selling cheap salad formulas (salad, drink, dessert) between around 3 and 7 euros.
