Lunar Rilles
Here is the paper that describes and analyses the work, and here is her Atlas of Lunar Sinuous Rilles. Each rille is numbered, and IAU name given when one exists; these numbers - H1 to H195 - should be the designation used to refer to lunar rilles. Debra includes lengths, depths, widths and other data, as well as LRO images for each rille. Fantastic work!
- Is there a catalog for LINEAR rilles too? - DannyCaes Jan 20, 2018
An attempt to create a much more comprehensive ABC of officially IAU-named and unofficially named Linear, Concentric, Craterfloor-Concentric, and Sinuous Rilles (on both the moon's nearside and farside)
Over time these will be classified as linear, concentric (basin), craterfloor-concentric, sinuous or other. You can help classify them - look at the image and decide which they are - and add your ID by typing four tildes (~) ! And if you disagree with a previous classification add what you think is a better one; use question marks as needed.
About discontinued IAU names
These names were part of the IAU nomenclature of Named Lunar Formations however they were not printed, or printed differently on the System of Lunar Craters charts. Since the extent to which the IAU accepted the changes to rille naming and numbering made in the SLC has never been clear, the current approval status of these names is unknown.
- Most of the additional (unofficially named) linear and sinuous rilles are discoveries from Danny Caes (detected while exploring the LROC ACT-REACT QUICK MAP of the entire moon's surface) (the "Big Shadows" version).

Additional notes
- Most of the cobweb-shaped appearances on the floors of the lunar farside's large Floor-Fractured Craters never received official names. A name such as Rimae Komarov for the system of "rilles" on the floor of the Floor-Fractured Crater Komarov is not an exact designation. On the other hand, it's a useful name.
- October 24th, 2017. Just discovered something which looks like an "upside-down" rille, or very thin ridge, at 11°30' South / 34°05' West (west of the arc-shaped hill Herigonius Nu). - DannyCaes Oct 24, 2017 (see the Big-Shadows WAC close-up in the LROC QuickMap: http://bit.ly/2zlb9Wi ).
