I have a few albums on mp3 that play fine when I am at my computer but just are not loud enough to sound good on my mp3 player.
I want to know if there is any way to add a bit of "gain" to a group of mp3s which sound too quiet.
I should add that the mp3s are the only thing I have to work with as the 2 BoltThrower discs I want to hear have become damaged over the years. No chance to rip them again.

Get MP3Gain, an open source software which does the job nicely.
From Wikipedia:
MP3Gain Homepage: Click!
Added:
Have you tried to rip the damaged discs using Exact Audio Copy? It's an excellent freeware known for its ability to rip severely damaged audio Compact Discs. It has been very useful for me several times...

You're welcome. What I like about MP3Gain is that it's a lossless process which doesn't involve re-encoding which would make your MP3s only sound worse.

EAC is a good program. I used to use it to copy/rip/making disc images of freely circulated live shows from punk bands and stuff. good program.

I didn't like EAC myself. Sure. It's good if you demand bit perfect or sometimes if you're trying to rip a damaged disc but otherwise, just about any ripper will do. EAC had too many settings that were unexplained and I didn't feel like going looking for the answers. Unless you have really good audio equipment and you know what to listen for, you aren't gonna notice a difference anyway.

+1 MP3Gain. Very easy to use.
Don't push it too far or you will get clipping on the loud parts.

There are some pretty straightforward guides to EAC available at Hydrogenaudio. I know it can look complicated, but you can ignore most of the advanced options and still get it set up for secure ripping. It shouldn't take more than 30 mins to work through a tutorial and get it configured properly. If you're ripping a significant number of CDs then I think it's well worth it.
One great thing about EAC is that there are utilities around to configure and automate the ripping process. I use REACT, and basically just have to pop in the disc and hit one key to get it to securely rip a CD, create both a FLAC image and split MP3s (in different directories), apply ReplayGain tags, create a cuesheet, download album art, and embed the cuesheet, art and EAC log in the FLAC image. This has saved me a lot more time that it took to set up.
As for not noticing a difference, I think glitches due to bad ripping are one of the most obvious defects you can get. Scratched/dirty CDs ripped without decent error correction will usually have problems that are easy to hear even on laptop speakers. A secure rip using EAC gives you peace of mind; you aren't going to notice problems later and have to dig out the CD and repeat the process.

^ Well, all of my CDs are pretty much pristine. I buy them, rip them (with CDex at 320) and put them back int he jewel cases. Many of my CDs have only been used once (to rip them).
At 320 (MP3), the only thing that would really be better is lossless (And my player can't read any of the lossless formats without Rockbox). I know I take a small hit using MP3 but the best headphones I have at the moment are Sennheiser HD497s and my sound card is a cheap Soundblaster. I've been relatively pleased with 320 MP3. I use FLAC for my absolute favorite stuff. But I still prefer the simplicity of something like CDex. The only CD I have that has serious errors on it is Metallica's And Justice For All. And I hardly listen to that.
Honestly. I'm pretty picky about sound quality and I don't notice a difference between 320 and FLAC with my equipment. If I had better stuff, maybe I would.

I do the same thing these days. Unfortunately other people don't, and a lot of the used CDs I buy from eBay are in pretty dodgy condition.
Nothing wrong with CDex, the top reason why I use EAC is that its automation (using REACT) makes ripping a quicker process. From what I've seen CDex is very good at accurately ripping CDs. If it fails to rip in CDex then chances are you aren't going to have much more luck in EAC.
I don't notice a difference either, and I doubt I would even if I spent a fortune on audiophile hardware. I stick with FLAC for peace of mind, and because I can transcode it into different formats in the future without re-ripping or loss of quality.
At the moment I automatically create normalised LAME -V4 MP3s for portable use when I rip. If I bought an MP3 player with more than 4Gb memory then I'd probably want higher quality, maybe if I bought an iPod I'd want everything in AAC. It's nice to have the FLAC files handy for mass transcoding, just set it running overnight and I'd have a copy of my music in a different format by morning.
At the moment my whole collection still fits comfortably on a single 750Gb drive, with storage so cheap there isn't much of a disadvantage to using lossless.
