Help! I’m a Prisoner in the Library! by Eth Clifford, 1979.
Harry Onetree is taking his two daughters, Mary Rose and Jo-Beth, to stay with their aunt on a snowy evening because their mother is about to have a baby and will soon be in the hospital. But, Harry has a habit of being careless and doing things at the last minute. In spite of practical Mary Rose’s warning that they’re running low on gas, Harry doesn’t stop to get any until they finally run out, and he has to hike through the snow back to the last gas station they passed.
Before their father gets back, Jo-Beth, the younger sister, declares that she has to go to the bathroom. Long-suffering Mary Rose finds one for her in a nearby library just before closing time. But, it’s not an ordinary library. It’s actually an old mansion which has been converted into a branch library for children. It has some fantastic displays, including an old wooden wagon called a “kid hack” which was once used to carry children to school, like a school bus. Unfortunately, the girls get distracted by this strange library. The girls forget about the library closing, and the librarian, not knowing that they’re there, locks them in for the night.

Meanwhile, the blizzard outside is getting worse, and their father has returned to the car and realized that they’re missing. The girls try to call the police, but they refuse to listen, thinking it’s a prank. Melodramatic Jo-Beth thinks that they’re doomed to starve to death in the library, trapped by the blizzard. Then, the girls hear a mysterious “thump” from upstairs. It turns out that they’re not alone in the library . . .
This is the first book in the Mary Rose and Jo-Beth Mysteries. It is available to borrow and read for free online through Internet Archive.
My Reaction
The Mary Rose and Jo-Beth books are fun with the way Jo-Beth delights in imagining doom and gloom while Mary Rose tries to work out a practical solution to their problems. The books in this series are also frequently about something other than the immediate mystery that the girls face. In this case, the girls learn about the history of the old house, how it became a branch library, and how old buildings, even though they are beautiful and have a history to them, may face destruction if people don’t care enough about them or find a way to put them to some useful purpose.
Be a Perfect Person in Just Three Days! by Stephen Manes, 1982.

This is the last of the four books I have in this
Triple Trouble in Hollywood by Michael J. Pellowski, 1989.
Sandi doesn’t want to do it because it would be dishonest, but Randi and Mandy talk her into it. It’s partly to help Mandy, partly to get back at Tara for her rotten attitude, and partly for the chance to meet the heartthrob Judd Morrison who will also be in the commercial. Of course, as is always the case when the girls switch places, nothing goes as planned. But, to the girls’ surprise, their younger brother Teddy helps to make things better in the end.
Triple Trouble by Michael J. Pellowski, 1988.
But, Mandy’s snobbish attitude rubs Randi and Sandi the wrong way. Mandy doesn’t want to do anything because she might get dirty or break a nail, and she keeps bragging about how grown up she is compared with her not-much-younger cousins. The twins argue with their cousin, and they play tricks on each other. When Mandy takes advantage of acting skills and her similar appearance to the other girls to try spending time with a boy they like by pretending to be them, Randi and Sandi decide it’s the last straw! They decide to show Mandy that playacting is a game that three can play at.
But, everything goes wrong when Randi’s coach talks to her teacher about the championship game, and it turns out that her teacher is secretly a soccer fan. When Sandi arrives for the tutoring session and the teacher and coach tell her the happy news that “Randi” can play in the championship game, Sandi has no time to tell Randi about it and switch places with her again. Will their hoax be exposed? Will the girls be able to switch places again in time to save the championship?
