Dear me! The “Downton Abbey” movie trailer is here, and oh, it’s a tantalizing montage of our favorite British mansion in all its delectable primness. But we must be patient; the film doesn’t hit theaters till the fall. Don’t despair. As the Dowager Countess once said, “Stop whining and find something to do.”

Here’s a little something: Read some books that will prepare you for your first glimpse of the Crawleys on the big screen. There’s a book out there for just about every kind of Abbey-phile — history buffs, mystery readers, even cat lovers.

For history buffs

Anyone who has ever fancied herself as the wife of a British royal will want to dive into Anne de Courcy’s “The Husband Hunters: American Heiresses Who Married Into the British Aristocracy” (St. Martin’s). De Courcy writes that between 1870 and 1914, 454 young American young women married titled Europeans. Among these “dollar princesses” are Jennie Jerome (Winston Churchill’s mother), Consuelo Vanderbilt and May Goelet — all contemporaries of Downton’s Lady Cora. If you’ve read “The Buccaneers” by Edith Wharton, you’ll understand the author’s conclusions about the roles that mothers played in this strange game of transatlantic weddings.

For fiction fans

Greta Goldbaum, the heroine of “House of Gold” by Natasha Solomons (Putnam), is neither a dollar princess nor a Dowager Countess, but still she must grapple with societal and familial expectations when it comes to marriage. At 21, Vienna-raised Greta chafes against her arranged betrothal to an English cousin. Her fortunes change drastically with the start of World War I, when she becomes a vital link between her European banking family and the British institutions less affected by combat and inflation. The Goldbaums bear a strong resemblance to the historical Rothschild dynasty: “Money has no passport and every passport,” says Greta’s brother Otto. Readers who enjoyed Solomon’s “The House at Tyneford” will love this novel, also based on the connections between Mitteleuropa and the United Kingdom.

For lovers of stately homes

Blenheim, Chatsworth, Longleat, Knole: All of these great British homes appear in “The Country House: Past, Present, Future,” a splendid Rizzoli coffee-table book by David Cannadine and Jeremy Musson. While Cannadine writes frequently about the aristocracy, in this book there is at least a peek at the “downstairs” necessary for the proverbial “upstairs”: Kitchens, servants’ quarters, stables and more are on display in photographs from the National Trust and private collections. The book features essays on the changing role of the country house as well as a frank discussion of enslaved people and their roles at these estates.

For mystery junkies

“The Mitford Murders” by Jessica Fellowes (Minotaur) should make Abbeyphiles feel quite cozy, as Fellowes is the author of the five “Downton Abbey” companion books. (Her Uncle Julian is known to most of us as “Downton” creator Julian Fellowes.) The former Country Life columnist brings her experience living among the upper crust to this debut, set in 1920 Oxfordshire at the historical Mitford Family estate of Asthall. The fictional foil to the famous sisters is Louisa Cannon, whose position as a nursemaid and chaperone places her close to one of the family wordsmiths, Nancy Mitford, who is 16 at the time of the story. When a goddaughter of Florence Nightingale is killed on a train, Louisa and Nancy join forces to find out why. With nearly as much period detail as an episode of “Downton,” this delightful romp satisfies like a cup of strong nursery tea accompanied by a Battenburg cake.

For travel enthusiasts

Phoebe Taplin’s “Oxford Film Locations: A Walking Guide to Harry Potter and Others” (Pavilion) may not mention “Downton Abbey” in its title but this detailed resource takes readers through Bampton, known to us as the village of Downton; Cogges, site of Yew Tree Farm; and Shilton, site of the Red Lion pub. And the book fittingly encourages walking, with itineraries that always include stops for refreshment — important when you don’t have Daisy packing picnic hampers to put in the boot. The book’s remaining dozen or so walks, including those through “Harry Potter” and “A Fish Called Wanda” sites, may prove enlivening, if far less soul-enriching.

For cat-video addicts

The first “Downton Tabby” (Simon & Schuster), published in 2013 and written by Chris Kelly, hewed closely to the outline of a family saga set in a stately home. This year we have another, wholly different “Downton Tabby,” by Chris Ellis (Skyhorse). It’s a funny little book that promises to reveal “What Your Cat Really Thinks While You Watch TV.” Although again, patience is a must: The book is not out until September. Yes, the book is slight, but that’s because Your Cat speaks in captions, not essays. “I think I’m lying on the remote, but I’m too comfy to move,” thinks one stretchy feline and really — who among us has not thought the same from time to time?
