Another email from Pasi

I just received another email from Pasi! Like we guessed, we need more info in order to find out the meaning of the card that was already found. This email is even more puzzling and it doesn't have any direct coordinates where to look. Therefore, I post the pictures Pasi sent me hoping that someone would have an idea where it could be.

Can anyone get the hidden thing based on Pasi's email? We should get a hold of it as soon as possible so that it doesn't end up in wrong hands...

EDIT: The card has been found.

Here is Pasi's email:

Hi Beth!

Since my last email, I've been going through my notes and I think I found something! I remember hiding one part of the coded word in a library and I found these photos from my album (Luckily I was an enthusiastic photographer at the time). As you know, it's crucial to get that piece of information. Hopefully these images are helpful enough!

Interesting book. Especially the pages 212-213.

Saw this nice building just next to the library.

Yours Sincerely,
Pasi Liisola

Message #7, part 2

Here is another picture I managed to get and I think it somehow links to the previous image with the key. At least that is what I heard some people speculate over a cup of coffee. I'm not sure, but it might be still missing some info? Or, who knows?

Message #7, part 1

We are living strange times at work. The new "Divide and conquer" policy makes it even harder for me to get any new messages. Apparently the big guns of the company have discovered the importance of them. More specifically they have realized that these messages contain something that is not so beneficial for the business. Therefore, they are becoming increasingly suspicious with anything related to the messages and they are only giving little bits of information to one person at a time, hoping that no-one would grasp the big picture (other than themselves obviously).

Therefore, the picture below is the only thing I was able to find at this time. I know it should be used for something, but the rest of the something (whatever it is) was distributed to a different place, so I have no access to it at this time. But I'll keep working on it!

Message #6

Yet another message that I was able to snatch! This is at least as weird as the previous ones. No matter which way I turn it, I just can't recognize anything in it.

Message #4

I was able the get a hold of yet another message. It was a bit tricky though. They almost saw me downloading this from certain person's laptop, but luckily I got them fooled. I guess, all those spy movies are finally paying off.

It's pretty clear that there's something written in the image, but what?
