In some research, the researchers are not able to use random assignments to divide participants among groups. Instead, they compare preexisting groups, which results in a quasi-experimental design.
Random assignments are those which are given as a matter of chance to ensure fairness and equal opportunity for all participants. Here participants forming multiple groups are with similar characteristics. So all groups are the same at the start of the experiment.
A quasi-experimental design applies a non-random method, and subjects are assigned to preexisting groups. There are some situations where true experiments can't be used for practical reasons. In such cases, a quasi-experimental design is a suitable tool.

Explanation:
Throughout his life, books were vital to Thomas Jefferson's education and well-being. When his family home Shadwell burned in 1770 Jefferson most lamented the loss of his books. In the midst of the American Revolution and while United States minister to France in the 1780s, Jefferson acquired thousands of books for his library at Monticello. Jefferson's library went through several stages, but it was always critically important to him. Books provided the little traveled Jefferson with a broader knowledge of the contemporary and ancient worlds than most contemporaries of broader personal experience. By 1814 when the British burned the nation's Capitol and the Library of Congress, Jefferson had acquired the largest personal collection of books in the United States. Jefferson offered to sell his library to Congress as a replacement for the collection destroyed by the British during the War of 1812. Congress purchased Jefferson's library for $23,950 in 1815. A second fire on Christmas Eve of 1851, destroyed nearly two thirds of the 6,487 volumes Congress had purchased from Jefferson.
Through a generous grant from Jerry and Gene Jones, the Library of Congress is attempting to reassemble Jefferson's library as it was sold to Congress. Although the broad scope of Jefferson's library was a cause for criticism of the purchase, Jefferson extolled the virtue of its broad sweep and established the principle of acquisition for the Library of Congress: “there is in fact no subject to which a member of Congress may not have occasion to refer.” Proclaiming that “I cannot live without books,” Jefferson began a second collection of several thousand books, which was sold at auction in 1829 to help satisfy his creditors.
