Price R/A: These are the average prices in Rimor/Atlantean as of 1-Jan-2012, checked in the Global Market Search (GMS) terminal with a neutral player with access to Neutral, Clan and Omni shops.
For nanos with Avail=SLG, it's an estimate of the price in the Garden/Sanctuary for a player with Comp. Lit. around 235.
This is only intended as a rough guide to the nano's real value, although it will be very useful if you're completely unaware of nano prices and about to sell, for instance, a QL60 Instruction Disc (Summon Grid Armor Mk I) to the shop (big mistake!).

Avail = Availability:

• R - This nano is (or was) rollable in nanocrystal form. I've rolled it myself with ClickSaver either as mission reward or "item to find". Check the F link to get the rollability facts for this nano.
• SLG - Available in some SL garden or sanctuary. Check the notes for more info.
• D - Unrollable. RK Dynaloot according to Trajanaxis' list and/or other sources, may drop from mission bosses too.
• QR - Unrollable, Quest Reward.
• ur - Unrollable. Probably boss-loot unless there are specific notes for it.

For the unrollable nanos I've provided an (ID) link as well, because in some cases you can find users' questions & answers on how to get them in Auno's ID description. You may find R/A GMS prices next to the ID too.

RMW - Link to a LIVE Rimor Market Watch report for this nano and/or ID.
AMW - Same for Atlantean.
VP - "Visual Profession" nano: Agents can upload it.
