Trying to Post an Expandable Post

As u can see, my posts about books I have red can get really long and annoying for people who are not interested in these books or can not read in Latvian.

There is a hack, how to make expandable posts. With a little problem - even short posts will be expandable using the hack. (c) http://blogger-tricks.blogspot.com/search/label/expandable%20post%20summary

All posts posted before this one has the link "Viss raksts... / Read More..." now, but there is no more to read.

For the next short posts not having anything more to read while expanded, even with no bigger pictures ;) there will be BEIGAS / END at the end of the post.
Like this one:
BEIGAS / END
